Hello! The answer to your question is B, 26 feet.
We're asked what the height of the object is after 2 seconds. The quadratic function also is based off of the variable t, which is t seconds after it has followed. Therefore, t = 2.
Now, substitute 2 in for t in the equation.
[tex]h(t)=-16t^{2} +90[/tex]
[tex]h(t)=-16(2)^{2} +90[/tex]
[tex]h(t)=-16(4) +90[/tex]
[tex]h(t)=-64 +90[/tex]
[tex]h(t)=26[/tex]
Therefore, your answer is 26 feet.
Hope this helps!
